Answer:

The answers are given below.

Step-by-step explanation:

7. Simplified Fractions/Integers:

a. $ (25)^{\frac{-3}{2}} $

= $ (5^2)^{\frac{-3}{2}} $

= $ 5^{-3} $

= $ \frac{1}{5^3} = \frac{1}{125} $ is the required answer.

b. $ \bigg ( \frac{1}{7} \bigg )^{2} $

= $ \bigg( \frac{1}{7^2} \bigg) $

= $ \frac{1}{49} $ is the required answer.

c. $ \bigg ( \frac{1}{7} \bigg) ^{-3} $

= $ \bigg ( \frac{1}{7^{-3}} \bigg )$

= $ 7^{3} $ = 343 is the required answer.

8. Simplified Fractions:

a. $ \bigg( \frac{27}{8} \bigg ) ^{\frac{2}{3}}$

= $ \bigg ( \frac{3^3}{2^3} \bigg ) ^{\frac{2}{3}} $

= $ \bigg ( \frac{3}{2} \bigg) ^2  $

$ = \frac{9}{4} $ is the required answer.

b. $ \bigg ( \frac{4}{25} \bigg)^{\frac{-3}{2}} $

= $ \bigg ( \frac{2^2}{5^2} \bigg)^{\frac{-3}{2}}

= $ \bigg ( \frac{2^{-3}}{5^{-3}} \bigg ) $

= $ \bigg( \frac{5^3}{2^3} \bigg ) $

= $ \frac{125}{8} $ is the required answer.

9. Index Forms:

a. √3

= $ 3^{\frac{1}{2}} $ is the required answer.

b. ∛3

= $ 3^{\frac{1}{3}} $ is the required answer.

c. $\sqrt[6]{2} $

= $ 2^{\frac{1}{6} $ is the required answer.

d. $ \sqrt{5^3} $

= $ 5^{\frac{3}{2}} $ is the required answer.

e. $ \frac{1}{(\sqrt[3]{5})^2} $

= $ \frac{1}{5^{\frac{2}{3}}} $

= $ 5^{\frac{-2}{3}} $ is the required answer.

A business buys a computer for $3,000. After 4 years the value of the computer is expected to be $250. The value, v, can be rela
yuradex [85]

You are given two points in the linear function. At time 0 years, the value is $3000. At time 4 years, the value is $250. This means you have points (0, 3000) and (4, 250). You need to find the equation of the line that passes through those two points.

y = mx + b

m = (y2 - y1)/(x2 - x1) = (3000 - 250)/(0 - 4) = 2750/(-4) = -687.5

Use point (0, 3000).

3000 = -687.5(0) + b

b = 3000

The equation is

y = -687.5x + 3000

Since we are using points (t, v) instead of (x, y), we have:

v = -687.5t + 3000

Answer: d. v = -687.50 t + 3,000

AVprozaik [17]

Answer:

20 cans

Step-by-step explanation:

Eileen collected 78 empty cans to recycle

Carl collected 62 empty cans to recycle

They pack equal number of cans in 7 boxes

Therefore the number of cans in each boxes can be calculated as follows.

= 62 + 78/7

= 140/7

= 20

Hence there were 20 cans in each boxes
